Short guides from the Filvo team on everyday image and PDF jobs: shrinking a scan so it fits an inbox, exporting a transparent PNG, picking HEX from a screenshot, and when to keep PNG instead of converting to JPG.
The articles complement the tools — they cover size caps, format tradeoffs, and what stays on your device. Open a guide, then jump to the matching compressor, converter, or cutout page.
